After WWII and with the intensification
of the US Government repression and in the advent of McCarthyism,

US and particularly in Hollywood.

of articles and books are addressing this subject. One of them is:
Radical Hollywood – The Untold Story Behind America’s Favourite
Movies! , by Paul Buhle and Dave Wagner, published by New Press,
2002.
